1：这个问题都被大家玩烂了，这里我也记载一下，方便以后脑补：

我是测试Hbase创建数据表的时候遇到的这种问题，总之吧，window操作hadoop都会遇到这种问题：
1 第一步:自己配置window的环境变量(很明显应该是HADOOP_HOME的问题。如果HADOOP_HOME为空，必然fullExeName为nullinwinutils.exe。解决方法很简单，配置环境变量，)。 2 第二步:不想重启电脑可以在程序里加上： 3 System.setProperty("hadoop.home.dir", "C:\Users\Administrator\Desktop\hadoop-2.7.3\hadoop-2.7.3"); 4 比如我添加到此处： 5 @Before 6 public void init() throws Exception { 7 System.setProperty("hadoop.home.dir", "E:\hadoop-2.6.4"); 8 // 配置 9 config = HBaseConfiguration.create(); 10 // zookeeper地址 11 config.set("hbase.zookeeper.quorum", "master,slaver1,slaver2"); 12 // zookeeper端口 13 config.set("hbase.zookeeper.property.clientPort", "2181"); 14 // 通过工厂模式创建一个Connection 15 connection = ConnectionFactory.createConnection(config); 16 // 通过Connection获取表连接 17 table = connection.getTable(TableName.valueOf("user")); 18 } 19 第三步：去https://github.com/srccodes/hadoop-common-2.2.0-bin/tree/master/bin 20 下载winutils.exe文件复制到自己的E:hadoop-2.6.4in目录里面。 21 第四步：重新运行程序就OK了，问题解决。
